CHAPTER 1 INTRODUCTION
1.1 GENERAL INFORMATION
The Observer Wristop Computer is a reliable high precision electronic instrument,
intended for recreational use. The outdoor enthusiast who enjoys venturing in sports like
skiing, kayaking, mountain climbing, hiking and biking can rely on the Observer’s accuracy.
NOTE: The Observer should not be substituted for acquiring measurements that require
professional or industrial precision and should not be used to acquire measurements
when skydiving, hang gliding, paragliding, gyrocopter riding and flying small aircraft.
The Observer is available in three different material combinations:
Observer Sr with stainless steel housing and elastomer strap, Observer St with stainless
steel housing and stainless steel / elastomer bracelet and Observer Tt with Titanium
housing and Titanium / elastomer bracelets. All material versions have identical functions
and operation.
1.2 CARE AND MAINTENANCE
1.2.1 Care of the Suunto Observer
Only perform the procedures described in this manual. Never attempt to disassemble or
service your Suunto Observer. Protect your Suunto Observer from shocks, extreme heat
and prolonged exposure to direct sunlight. Avoid rubbing the Suunto Observer against
rough surfaces as this may scratch the face. If not in use, your Suunto Observer should be
stored in a clean, dry environment at room temperature.
The Suunto Observer can be wiped clean with a lightly moistened (warm water) cloth.
If there are stubborn stains or marks, you can apply mild soap to the area. Do not expose
the Suunto Observer to strong chemicals such as gasoline, cleaning solvents, acetone,
alcohol, insect repellents, adhesives and paint, as they will damage the unit’s seals,
case and finish. Make sure the area around the sensor is kept free of dirt and sand. Never
insert any objects into the sensor opening.
5
1.3 WATER RESISTANCE
Suunto Observer is tested with ISO (International Organization for standardization,
www.iso.ch) standard 2281. This means that the product is water-resistant. In addition to
the term ‘water resistant’, Suunto Observer is marked with an indication of a test
overpressure given as a depth in meters (100 m/330 feet). This indication, however,
does not correspond to a diving depth but refers to the pressure at which the water
overpressure test was conducted.
This means that you cannot dive to a depth of 100 m/330 ft. with your Suunto Observer.
Rain, showering, swimming and other normal exposure to water will not affect its operation
but the buttons shall not be pressed if exposed to water in any circumstances.
NOTE: Suunto Observer wristop computers must not be used for diving.
1.4 BATTERY REPLACEMENT
Suunto Observer operates on a 3-Volt lithium cell, type: CR 2032. The life expectancy
is approximately 12 months in the Time mode.
A low-battery warning indicator is activated on the display when approximately 5–15
percent of the battery capacity is still available. When this occurs, you should replace
the battery. However, extremely cold weather may activate the low battery warning
indicator even though the battery is still fully operational. If the battery warning indicator is activated in temperatures above 10°C (50°F), replace the battery.
NOTE: Heavy use of the backlight, altimeter and compass will significantly reduce
battery life.
You can replace the batteries yourself as long as you do it properly to avoid any leakage
of water into the battery compartment or computer. Always use original battery
replacement kits. (They include a new battery, battery lid and O-ring.) You can purchase
the battery kits from official Suunto retailers.
NOTE: When replacing the battery, also replace the battery lid and O-ring. Never use
the old ones.
6
NOTE: Change the battery at your own risk. Suunto recommends
you to have the batteries changed in official Suunto
services.
To replace the battery:
1. Insert a coin into the slot located on the battery
compartment cover on the backside of your Suunto
Observer.
2. Turn the coin counterclockwise until it is aligned
with the open position marker.
3. Remove the battery compartment cover and the
O-ring, and discard them. Ensure that all surfaces
are clean and dry.
4. Remove the old battery carefully.
5. Place the new battery into the battery compartment under the metal contact clips, with the positive side facing up.
6. With the O-ring in the correct position, replace the
battery compartment cover and turn it with the
coin clockwise until it is aligned with the closed
position marker. Do not press onto the battery compartment cover while turning it with a coin.
NOTE: Perform battery replacement with extreme care
to ensure that your Suunto Observer remains water
resistant. Careless battery replacement may void
warranty.

CHAPTER 3 ALTIMETER MODE
The Altimeter provides you with:
• An adjustable unit of measure either meter or feet: meter range -500 to 9000; ft
range -1,600 to 29500;
• A resolution of 1m or 3ft;
• A display up-date on the rate of vertical movement in intervals of 1 second for 3
17
minutes, then every 10 seconds or less;
• A logbook, recording 99 single logs including the total ascent, total descent, number
of runs, and the duration of the log.
• Altimeter-Barometer use feature
To view and use the Altimeter function:
Press the [MODE] button until the indicator is directly below ALTI.
In the ALTIMETER mode the fields display data as shown in Fig. 3.1:
a) The vertical ascent or descent rate in meters or feet per min;

measure selected);
c) Altimeter mode and altimeter use indicator;
d) The current time; and
e) The outer circumference of the LCD graphically displays lit segments representing
the altitude over a full thousand meters or feet (one complete circle is equivalent to
1000 m or 1000 ft)
3.1 ALTIMETER-BAROMETER USE
The Observer can be used as either a weather station or altimeter. This operating
feature is chosen in the setup process while in the altimeter or the barometer mode. To
toggle between these icon positions, hold the [Select]-button in for 2 seconds and then,
press the [Quick] or [On Off]-button to lock in one of the functions.
The icon for this function is displayed under the corresponding mode indicator (ALTI or
shape. The position of the icon indicates whether the Observer
BARO) in a half-moon
is being used as a weather station (BARO) or altimeter (ALTI).
NOTE: This is different than moving between ALTI and BARO main modes.
THIS IS IMPORTANT.
The use indicator has to be in ALTI position, otherwise the altitude display
is fixed.
18
When Altimeter Use is selected:
• The unit will be used as an altimeter.
• All pressure changes are interpreted as altitude changes.
• The sea level pressure reading displayed in the barometer mode will not change,
even though the absolute pressure reading will change.
When Barometer Use is selected:
• The unit will be used as a weather station.
• The unit interprets all pressure changes as being due to a change in the weather.
• Measured changes will affect only the pressure reading displayed in the barometer
mode. Both sea level pressure and absolute pressure reading will change. These
changes won’t affect the altitude reading in the altimeter mode while barometer use
is activated.
The Observer leaves the factory set to be used as an altimeter.
3.2 SETTING THE ALTIMETER
In setting the Altimeter, there are two processes that can be performed:
• The Reference Altitude (known altitude at the current location); and
• The Altitude Alarm (signals you when a certain programmed altitude is reached).
IMPORTANT NOTE:
In order to set the altitude in the Altimeter mode, the altitude must be known. That
information can be found by utilizing a topographical map, identifying the current
location with the associated altitude marked. You can proceed and follow the
instructions, setting the altimeter, provided in the section below.
If the Altitude is not known, you can set the sea level pressure in the Barometric mode.
Refer to Chapter 4, Setting the Sea Level Pressure.
Setting the Sea Level Pressure will adjust the altimeter to the current altitude within
approximately ten meters or 30 ft.
19
For information regarding the effect of air temperature on altitude measurement refer to
the last section of Chapter 3.
Information on the current sea level pressure can be obtained through newspapers,
local news and radio weather reports, the local airport facility or through the Internet
under local weather.
To set the altimeter:
1. In the altimeter main mode (mode indicator below ALTI), Press the [SELECT] button
for 2 seconds. In the top field, the text “RE” (indicating reference altitude) displays. In
the middle field, the current altitude displays. In the bottom field the half-moon
shaped use indicator under the indicator bar will begin to flash (Altimeter-Barometer
use feature) and the text “USE” will appear.
2. Press either the [ON OFF] or [QUICK] button to toggle the icon to the position under
“ALTI” (for altimeter use) or “BARO” (for barometer use).
3. At the desired preference, press the [SELECT] button to move to the next setting. In
the middle field, the reference altitude value will begin to flash.
4. Press either the [ON OFF] button to scroll the value up or the [QUICK] button to scroll
down.
5. At the desired reference altitude, press the [SELECT] button to move to the next
setting (Altitude Alarm setting). In the top field, the “ON” or “OFF” will begin to flash.
6. Press either the [ON OFF] or the [QUICK] button to toggle between the “ON” and
“OFF” for the Altitude Alarm.
NOTE: An activated altitude alarm is indicated with an alarm symbol.
7. At the desired setting, press the [SELECT] button to move to the next setting. In the
middle field, the alarm altitude will begin to flash.
8. Press either the [ON OFF] button to scroll the value up or the [QUICK] button to scroll
down.

bottom field. To stop a logbook recording, you must be in the altimeter mode and
perform two short presses of the [ON OFF] button again.
The memory capacity is 99 logs, each at maximum 20 hour duration. After recording
the 99th logbook, the Observer writes the next logbook over the logbook number 1 (the
oldest log) and then continues in numeric order.
The logbook is recording in 10-second intervals, which is quick enough for all activities.
It is not possible to view the individual values of the logbook.
NOTE: You can be in other modes while recording. To indicate logbook-recording
activity, the Observer will display the text “LOG” flashing in the bottom field.

recording(s).
3.6 EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT
The atmospheric pressure means the weight of air mass above the observer: at a higher
altitude there is less air than at a lower altitude. The principle of an altimeter is to
measure the different air pressure between different altitudes.
The outside temperature affects the air weight. Consequently the air pressure difference
between two altitudes is also dependant on temperature.
The altitude calculation of the Observer is based on the air pressure at certain normal
temperatures. Each altitude has a definitive normal temperature. The normal
temperatures at each altitude are presented in Table 1.

(ºF)
The altitude measurement error caused by an abnormal temperature gradient can be
approximated as follows. If the sum of the temperature offsets from the normal
temperatures determined at two different altitudes is 1 ºC, the altitude
difference calculated by the Observer is 0.2% off the real altitude
difference (When using imperial units the offset factor is 0.11% / 1 ºF). This is because
the real temperatures are not always the same as the normal temperatures. A higher
than normal temperature causes the calculated altitude difference to be smaller than
the real altitude difference (your mountain ascent was actually higher). Consequently, a
lower than normal temperature causes the calculated altitude difference to be larger
than the real altitude difference (you did not ascend quite as high as displayed).
Table 2 shows an example in which the temperature offsets are positive. In this example,
the reference altitude is set at 1000 m. At 3000 m the altitude difference is 2000 m and
Observer shows 80 m too little (20 ºC * 2000 m * 0.002/ºC = 80 m). Your actual altitude
is thus 3080 m.
All Suunto products with altimeter are temperature calibrated. This means that at
constant pressure, the reading of the pressure sensor is always the same independent of
the unit’s own temperature. However, the air temperature can still effect the altitude
readings as described above.

Table 3 shows an example in which the temperature offsets are negative. This time
imperial units are used. The reference altitude is set at 3280 feet. At 9840 feet the
altitude difference is 6560 feet and Observer shows 100 feet too much (-14 ºF * 6560 ft
* 0.0011/ºF = -100 ft). Your actual altitude is thus 9740 ft.

pressure. (Press the [ON OFF] button to toggle between the two values); and
d) The outer circumference of the LCD graphically displays lit segments of the atmospheric pressure over 100 hPa or 1 inHg where one complete circle is equivalent to
100 hPa/1 inHg, depending on the unit of measure chosen.
NOTE: The absolute pressure is the actual pressure in any location at any given time.
The sea level pressure is the corresponding pressure at sea level.
NOTE: The absolute pressure is depending on current altitude and weather.
4.1 SETTING THE SEA LEVEL PRESSURE
Setting the sea level pressure can be used in setting the altitude measurement if the
altitude is not known.
To set the sea level pressure:
1. In the barometric main mode, press the [SELECT] button for 2 seconds. The top field
displays the text “SEA”; the middle field displays the current sea level pressure, and
under the indicator bar
in the bottom field the half-moon shaped use indicator
will begin to flash (Altimeter-Barometer use feature) and the text “USE” will appear.
2. Press either the [ON OFF] or [QUICK] button to toggle the icon to the position under
“ALTI” (for altimeter use) or “BARO” (for barometer use).
3. At the desired preference, press the [SELECT] button. In the middle field, the sea
29
level pressure value will begin to flash.
4. Press the [ON OFF] button to scroll the value up or the [QUICK] button to scroll down.
5. When the current sea level pressure is displayed, press the [MODE] button to accept
the changes and exit.
Once you complete this process, the altitude measurement on the Observer should be
correct within a range of approximately ten meters or some tens of feet.
NOTE: Information on the current sea level pressure can be obtained through
newspapers, local news and radio weather reports, the local airport facility or through
the Internet under local weather.
NOTE: Setup mode will automatically be released if left idle for more than one minute.
4.2 4-DAY MEMORY SUB MODE
In the Barometric mode, PRESS the [SELECT] button once to enter this sub mode. This
feature allows you to follow changes in pressure that will assist you in forecasting
changes in weather condition (i.e. storms).
In the 4-day memory mode the display fields are as shown in Fig. 4.2:
a) The top field displays the day of the week;
b) The middle field displays the sea level pressure;
c) The bottom field displays the time corresponding to the pressure in the middle field
and the text “MEM”; and
d) The outer circumference of the LCD graphically displays the atmospheric pressure
where one full circle equals 100 hPa or 1 inHg.
To view the information compiled in the 4-day memory:
Press the [QUICK] button to scroll through the history of recordings beginning with
increments of one hour for the first six hours, after that increments are 6 hours.
Press the [ON OFF] button to scroll back up to the most recent recording.

4.3 BAROMETRIC TREND INDICATOR
The Barometric Trend Indicator is located in the top left corner of the LCD display. When
the barometer use feature is on, this indicator is displayed in all main modes to provide
you with an indication of upcoming weather conditions. If altimeter use is activated, the
trend indicator is not shown.
The Barometric trend is comprised of two lines forming an arrow. Each line represents a
3-hour period. The right line represents the last 3 hours. The left line represents 3 hours
prior to the last 3 hours. The line can indicate 9 different patterns in the barometric
trend. Examples:
Situation 6-3 hours ago
Situation last 3 hours
Dropped heavy (>2 hPa/3hours)
Dropping heavy (>2 hPa/3hours)
Remained stable
Rising heavy (>2 hPa/3hours)
Risen heavy (>2 hPa/3hours)
Dropping heavy (>2 hPa/3hours)
CHAPTER 5 COMPASS MODE
The Compass provides you with:
• A resolution of 1º for the bearing, and ±5º for North-South direction;
• A bearing tracking mode that’s used to indicate desired direction and actual bearing.
• A declination correction feature; and
IMPORTANT NOTE: To reach as accurate compass readings as possible, keep the
Observer in a level position.
In the compass mode, the fields display the following data as shown in Fig. 5.1:
a) The top field displays a cardinal or half cardinal point abbreviation;
31
b) The middle field displays bearing in degrees;
c) The bottom field displays current time; and
d) The outer circumference of the LCD graphically displays lit segments representing
a North-South arrow; (one-lit segment indicates North, three-lit segments indicate South)
To view and use the Compass function:
Press the [MODE] button until the mode indicator is directly below COMP.
The compass display is active for 45 seconds at a time. After this, the compass enters
“sleep” mode for power saving and an “- - -°” indicator appears in the middle field. To
reactivate the compass, press the [QUICK] button.
NOTE: Compass readings should be performed away from objects possessing sources
of magnetism. Avoid large metal objects, power lines, loudspeakers, electric motors etc.
This type of disturbances cause relatively often need to calibrate the compass.
Always take bearings in the open air, not inside buildings, tents, caves, or other
shelters.
5.1 BEARING TRACKING SUB MODE
In the compass mode you can select to change from the cardinal point mode to the
bearing track mode and utilize the bearing lock feature for tracking purposes.
In the bearing tracking mode, the fields display data as shown in Fig. 5.2:
a) Locked bearing in degrees
b) Actual bearing in degrees
c) Current time
d) The outer circumference of the LCD graphically displays the difference of the locked
and actual bearing. The end of the lit segments indicates the direction of the
bearing to be tracked.
To activate the bearing tracking mode press the [ON OFF] button twice. If active, press
the [ON OFF] button twice to deactivate.
32
To set the bearing lock
1. Press the [SELECT] button for 2 seconds to start the setup process. Located in the
middle field, the actual bearing in degrees will begin to flash.
2. Turn the Observer to the desired direction. Lock the bearing displayed by pressing
the [QUICK] button.
3. To adjust the locked bearing, press the [SELECT] button once, so that the locked
bearing in the top field starts to flash. Then adjust the value with the [ON OFF] and
[QUICK] buttons.
4. At the desired bearing to track, press the [MODE] button to accept the changes and
exit the setup program.
NOTE: The above steps can also be performed in the main compass mode.
Setup mode will automatically be released if left idle for more than one minute.
5.2 DECLINATION ADJUSTMENT SUB MODE
The Observer allows you to compensate for the difference between true north and
magnetic north by adjusting the compass declination.
In the Compass mode, press the [SELECT] button once to enter this sub mode. The
display is shown in Fig. 5.3:
• The top field displays the current declination direction where OFF = no declination;
W = West; E = East;
• The middle field displays declination in degrees; and
• The bottom field displays the text “dEC”.
5.2.1 Setting the Local Declination
1. Press the [SELECT] button for 2 seconds. In the top field, the text “OFF” will begin to
flash.
2. Press the [ON OFF] or the [QUICK] button to select the declination direction in the
top field.
33
3. Press the [SELECT] button to move to the next setting. In the middle field, the
degrees will begin to flash.
4. Press the [ON OFF] button to scroll the degrees up or the [QUICK] button to scroll
down.
5. At the degrees desired, press the [MODE] button to accept the changes and exit.
Local Declination is now set.
NOTE: You can find the local declination in the maps of your area.
Setup mode will automatically exit if left idle for more than one minute.
5.3 CALIBRATING THE COMPASS
A compass calibration should be done whenever the Observer is exposed to a strong
magnetic source, extreme cold weather, the battery is replaced, or you suspect that other
environmental conditions have affected the compass readings. If you notice that the
compass is not showing the direction correctly, you should do the calibration.
NOTE: Calibrate the compass before you use it for the first time, and before you leave
for an extended outdoor activity.
To begin the calibration:
1. Press the [SELECT] button twice when in the main compass mode. The top field
displays the text “CMP”, and the bottom field displays the text “CAL” (Fig. 5.4).
2. Press the [SELECT] button for 2 seconds. In the middle field, the text “PUSH” will
begin to flash, alternating with the sign “-” (Fig. 5.5). This indicates the button
[QUICK / -].
3. Press the [QUICK] button to start calibration. The middle field displays 360º and the
LCD ring on the outer circumference light (Fig. 5.6).
4. Hold the Observer level and slowly rotate the device in a full clockwise or counterclockwise circle. As you turn, the lit LCD segments will turn off.
34
NOTE: For successful calibration, it is important to hold the Observer level during the
calibration process. This is simple to accomplish. For example, place the Observer on
an over-turned drinking glass on a table.
5. Within a minute of completing a full circle, the Observer will inform you whether the
calibration was successful by displaying the text “dOnE” in the middle field (Fig. 5.7),
or if the calibration needs to be repeated by displaying “PUSH” and “-” (Fig. 5.5).
NOTE: you may need to perform the rotating of the compass more than twice around for
the calibration to be completed.
NOTE: If the text “FAIL” appears in the middle field, the battery should be removed and
put back in before trying to proceed with the calibration process. The removal of the
battery will “reset” the unit.
6. Once the calibration is successful, press the [MODE] button to accept calibration.
Press the [MODE] button a second time to return to main compass mode.
The compass calibration is complete.
CHAPTER 6 FREQUENTLY ASKED QUESTIONS
How long does the battery last?
The normal lifetime expectancy is 12 months. Battery life depends mainly on how much
the backlight, the compass and the logbook are used. The low-battery warning symbol
appears on the display when 5 to 15 percent of battery capacity remains. Which gives
you plenty of time to safely change the battery.
Why is the altitude reading not changing even though I’m moving
in a vertical direction?
You are using the Observer as a barometer and the altitude is fixed. To change to the
altimeter use, enter settings in the BARO or ALTI mode. The first thing that you can set
35
is the choice between Altimeter/Barometer Use. Refer to Chapter 3, Altimeter-Barometer
Use.
Why does the vertical ascent/descent measurement show different
readings even though I am inside and staying in the same room?
Indoors, even small, unnoticeable air currents cause changes in air pressure. For example,
if you have a window open at the other end of your house, the air current may affect a
room at the other end of the building so little that you don’t notice it, but the sensors of
the Observer do. Because the Observer measures ascent and descent based on changes
in air pressure, it interprets these changes as vertical movement.
What happens after the 99th logbook?
After recording the 99th logbook, the Observer writes the next logbook over the logbook
number 1 (the oldest log) and then continues in numeric order.
What is the maximum capacity of total vertical ascent or descent
feet/meters in the logbook history?
The maximum figure that can be shown on the display is 39,999.999 representing feet
or meters depending on the unit of measurement set. This should be enough for most
users: 39,999.999 meters is roughly three-quarters around the globe.
What is the duration readout?
The duration readout tells you how many hours and/or minutes the event recorded into
the logbook lasted. For example, if you’re hiking from 1 p.m. to 6 p.m. and the logbook
is on during this time, the readout would show a duration of 5:00 hours.
Does the Observer show future trends in weather conditions?
No, the Observer continually accumulates data on barometric pressure and stores the
data of last 4 days. The barometric trends of the last 6 hour window is displayed
graphically with an arrow in the top field. The Observer does not make forecasts of the
36
future weather, it stores data that supports you doing this. Remember that estimating the
coming weather should be based on different signs of nature in addition to the barometric
trend.
What does “absolute pressure” and “sea level pressure” mean?
Absolute pressure is the actual pressure in any location at any given time. Sea level
pressure equals the corresponding pressure at sea level for a certain altitude that you are
at. For example, if you are at an altitude of 1,000 m/3,300 ft the absolute pressure
normally is around 900 hPa/26.60 inHg. The relative pressure at sea level would then
be around 1,013 hPa/29.90 inHg.
What is temperature compensation?
When the unit is temperature compensated, the temperature of the unit itself does not
affect the altitude measurement of the unit. The unit can be worn on your wrist or placed
on a table - it will in either case give you the proper altitude reading providing the
weather conditions have not changed. All Suunto Observers are temperature
compensated within the range -5 to 140 ° F / - 20 to +60 ° C. Refer to Chapter 3, Effect
of Air Temperature on Altitude Measurement.
Why is the compass not working correctly?
It has been exposed to external electromagnetic disturbance and has to be calibrated.
Refer to Chapter 5, Calibrating the Compass.
Where do I find the correct declination for my area so I can set my
Observer?
Local declination, either E or W, is usually marked on maps with either one-degree or
half-degree accuracy.
When should I operate the Observer in Altimeter Use and when in
Barometer Use?
Altimeter Use (half-moon
indicator below ALTI in the mode bar) is your choice when
37
you want to measure the altitude and there is vertical movement included in your
activity. Barometer Use is suitable for weather measurements.
A natural way to alternate between Altimeter/Barometer Use during a hike is to use the
Observer as altimeter when moving and as barometer when camping (no vertical
movement expected). This way you will have more accurate information on both altitude
and weather. Refer to Chapter 3, Altimeter-Barometer Use.
NOTE: The modes TIME, ALTI, BARO, and COMP are different from the main operational
USE between Altimeter and Barometer.
What do the LCD segments on the circumference mean?
In the Altimeter mode, one full circle equals 1,000 meters or 1,000 feet; therefore the
segments on the circumference graphically show you the altitude over a full thousand.
In the Barometer mode, one full circle equals 100 hPa or 1 inHg, and the segments
indicate the pressure over a full hundred hPa or over a full inHg.
In the main Compass mode, the segments indicate the North and South (one-lit segment
indicates North, three-lit segment indicate South). If you have set the compass to track
a certain bearing, the segments on the circumference indicate the difference between
the direction in which you want to go and your actual bearing.
